A couple of 14-year-old computer whizzes have the Bank of Montreal upgrading its security after the teens hacked an ATM machine.
Matthew Hewlett and Caleb Turon, both Grade 9 students, found an old ATM operators manual online that showed how to get into the machine's operator mode.
On Wednesday over their lunch hour, they went to the BMO's ATM at the Safeway on Grant Avenue to see if they could get into the system.
